Just have a question about when you should change the spark plugs on my Z I have 77 thousand miles on it. I keep up with the maintenance very well but have been thinking about doing this

75,000 miles. You just missed it. Sorry.

 

I recently bought my 2003 Z with 58k miles. Soon after I had a P0301 cylinder #1 misfire due to a coil and while I was at it I pulled all of the plugs to inspect them. The stock gap is 0.043" and all of the plugs showed significant wear (rounding of the electrode tips, some build up) plus the gap on all of them had changed to 0.049"-0.052". Based on what I saw on my car I would say you need to go a head and change your plugs. It is easy to do yourself in a couple of hours for someone that has never done it before and it does not cost much either.

 

Hey man, not to be a douche or anything, but I've been seeing your posts for a while in the short time I've been on these forums, and I was just wondering, have you EVER posted something constructive? Just wondering though, have a nice day.

 

he actually does, when people aren't asking the same questions over and over and over. trust me, the answers to this question are easy to find on this forum.

every now and then you will find a real answer buried in his sarcasm as well.

 

Actually, the manual states that the spark plugs should be changed at 105,000 miles.

 

actually it says both. it all depends on one's driving schedule/style.

 

he was nice to me about my drag thread and told me he hopes to see me on the list soon so thats pretty nice...
